What are the basic rules of optimal design EMC?
The three basic rules of optimal design of an electromagnetically compatible equipment are: The equipment does not cause interference to other equipments. The equipment is not susceptible to emissions from other equipments. The computer does not cause interferences to itself.
What is the lowest frequency that is of practical concern for the EMC Directive?
Q. What is the lowest frequency that is of practical concern for the EMC directive? A. That would be 150 kHz for conducted emissions.
What form of noise is produced as a result of the random thermally induced motion of the atoms in a material?
What form of noise is produced as a result of the random, thermally induced motion of the atoms in a material? Johnson noise.
What are the sources of interference?
The two most common causes of interference are transmitters and electrical equipment.
- Transmitter interference. Communication systems that transmit signals capable of generating interference include amateur radios, CBs and radio and television stations.
- Electrical interference and your TV.

What is the standard frequency range for EMC?
The EMC standards generally cover the range from 0 Hz to 400 GHz. Currently, however, not all frequency ranges are completely regu- lated. The first important frequency range is the range around the power network frequency, which in Europe is 50 Hz.
How does EMC affect the performance of an electronic product?
The function and performance an electronic product can easily be affected by external and internally generated EMC phenomena. As an example, if your internal power supply regulation is too noisy, that can adversely affect sensitive analog measurements (for sensor products), or lower the performance of a radio transmitter (for wireless products).
Are there any accredited labs for EMC testing?
Recently announced new rules for EMC test labs by the FCC mean that transmitter ‘certification’ testing will only be accepted from recognized and accredited test labs. Approximately 2/3 of the 1000 or so test sites registered with the FCC are currently not accredited.
